To all whom it may concern:

Be it known that I, CLARENcE'S'roNE, a citizen of the United States,residing at Stroudsburg, in the county ofMonroe, State of Pennsylvania,have invented a new and useful Cotter-Pin Extractor; and I go'h'erebydeclare the-following to be a ful, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to a new and useful cotter pin extractor, and anobject of the same is to provide a rod member having means to engage theeye of the cotter pin, in combination with an impact member, the latteroperating to strike an abutment several hammer blows, in order toextract the cotter pin,

In practical fields, the details of construction may necessitatealterations, falling within the scope of what is claimed.

The invention comprises further features and combinations of parts, ashereinafter set forth, shown in the drawings, and claimed.

In the drawings Figure 1 is a view in elevation of a portion of apulley, showin the same fastened on by a. cotter pin and illustratingtheextractor connected-thereto for removing the Fig. 2 is a view partlyin section and Referring more especially to the draw- 1ng' s, 1designates a portion of apulley, which is secured on asuitable shaft 2,by means of a cotter pin 3 passing through the hub 4 'of the pulley.Frequently it is very- Y diflicult to remove cotter pins, owing to theirbinding in the openings of a hub of a pulley and the shaft. Hence, it isthe purpose of this invention to provide means to overcome this bindingaction, and-extract the cotter pin. This extractin means consists of anelon ated steel rod 5 aving a hook 6 at one en to engage the eye of thecotter pin when extracting the same. The other end of the rod has anenlargement'l causing Specification o fLetters Patent.

a shoulder 8 to be formed. This enlarge- 5b ment merges into a taperingblade 8*, whlch serves as means for straightening the ends 9 of thecotter pin, in order to render it easier to extract or remove the pin.An impact member 10, which may be of any suitable shape or constructionand constructed from any suitable material, referably steel is carriedby the elongated rod 5, which telescopes through the longitudinalopening 11 of the impact member. The impact member is loosely mountedupon the rod, and when the hook. 6is in engagement with the eye of thecotter pin, the impact member may be moved or reciprocated severaltimeson the sive impact against theshoulder 8, thereby removing or extractingthe cotter pin.

It is obvious that the device may also be used for inserting cotterpins. A cotter pin havin once been started in the hole in which t isintended to be inserted, the book 6 may be made to engage the eyethereof, whereupon the member 10 may be impacted against the-cotter pinhead to drive the cotter pin in the hole, the hook 6 the whil e 7serving to keep the rod 5 connected with the pin .and directing the vimpact mber against the head thereof.

. The invention having been set forth,'what is claimed as new anduseful, is

A cotter pin extractor comprising a rod member having a hook formed atone end for engagement with the eye of a cotter pin and having anabutment formed at the "other end, and an impact member through '85which the rod member passes and which is movable longitudinally fromsaid abutment to the hooked end, whereby a cotter pin may be insertedbysuccessive impacts upon its head or withdrawn by successive impacts Intestimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
